Avaya/Nortel has released a technical support bulletin documenting an issue that may arise regarding the NVRAM (flash memory) on the Ethernet Routing Switch 5500.
Apparently the auto-save feature may be exhausting the number of writes that the physical flash memory is capable of. If the switch is configured with MAC address security, a feature that could possibility be causing the auto-save feature to write the configuration hundreds if not thousands of times, the flash memory may surfer from extreme “memory wear” and cease functioning properly.
Thankfully there is a “second” NVRAM flash block available.
I would highly suggest that everyone review the bulletin for themselves.
It might be wise to disable the auto-save feature and have the technicians/engineers manually save any configuration changes when necessary (similar to how Cisco switches/routers work).
Cheers!
Hi Michael
Thanks for the information, I followed the instruction, but the nvram all seems good, returning with no errors, I did make block 2 active as well and try the same, again this returned with no errors, this is a strange one !

2. – To copy config nvram command does not save
3. – As I keep the two NVRAM
